Correlations between compulsory drug abstinence treatments and HIV risk behaviors among injection drug users in a border city of South China.

Compulsory drug abstinence treatments (CAT) provided by the public security system have been one of the predominant methods of addressing drug abuse and HIV risks in China. This study assessed the association between CAT and HIV risk behaviors by surveying a community sample of 613 injection drug users (IDUs) at a city located in South China. The data indicated that the great majority of the participants (89.6%) had received the institutionalized treatments an average of 4.5 times. The study found that the number of compulsory drug abstinence treatments increased IDUs' HIV/AIDS knowledge. However, other HIV-related outcomes were not encouraging. The study found that the number of compulsory drug abstinence treatments was not related to an increase in condom use. Furthermore, the frequency of compulsory drug abstinence treatments was not related to needle/syringe sharing, but was positively associated with cooker/cotton/rinse water sharing and drug solution sharing. The number of compulsory drug abstinence treatments was positively associated with HIV status. In general, this study found little support that CAT has accomplished its goal in reducing HIV risks among injection drug users in the sample. Policy implications for reforming CAT are suggested.

Can variation in HIV/STD-related risk be explained by individual SES? Findings from female sex workers in a rural Chinese county.

Low socioeconomic status (SES) has been linked to HIV and sexually transmitted disease (STD) at a macro level because the majority of new cases of HIV infection in the world have been reported in underdeveloped or developing countries. However, empirical data on the relationship between individual SES and HIV/STD related risk have been mixed. Employing quantitative data from 454 female sex workers (FSWs), this study was designed to examine the profile of the study sample in terms of their individual SES, HIV/STD-related sexual risk across work locations with different social, cultural, and economic conditions; and to examine the relationship between work location and HIV-related risk behaviors, controlling for individual SES. We have shown in the current study that both SES and HIV/STD-related risk behaviors significantly differed by work location. However, the difference in individual SES was not sufficient to explain the difference of HIV/STD-related risk across the work locations. The findings underscore the need for effective prevention intervention efforts targeting FSWs in rural areas. Based on the findings, we also suggest that HIV/STD intervention efforts among FSWs should take the social and cultural contextual factors of their working environment (and sexual risks) into consideration.

Hepatoprotective effect of Hypericum japonicum extract and its fractions.

OBJECTIVE: To investigate the hepatoprotective activity of different parts of Hypericum japonicum against carbon tetrachloride(CCl(4))-induced hepatitis and alpha-naphthyl-isothiocyanate (ANIT)-induced cholestasis. MATERIALS AND METHODS: Mice were divided into groups and then administrated orally with solutions extracted from herbs before they were modeled in the experiments. Levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST) and total bilirubin (T-BIL) in serum were evaluated. HPLC fingerprint was used for phytochemical analysis of the extracts. RESULTS: The total aqueous extract of Hypericum japonicum had an obvious effect on the decreasing of AST, ALT and T-BIL levels in serum. The isolated fraction IV (F4) exhibited a preferable activity of ameliorating cholestasis, while Fraction V (F5) was more efficacious in protecting liver from injury. Chemical fingerprint indicated that F5 contained several flavonoids which might be the active chemicals against hepatotoxicity. CONCLUSION: Different fractions of Hypericum japonicum manifest different effect, indicating their different potentials as candidacies of new drugs.

HIV voluntary counseling and testing among injection drug users in south China: a study of a non-government organization based program.

HIV voluntary counseling and testing (VCT) programs are usually delivered by government health agencies in China. This study examined the feasibility of using a Chinese non-government organization (NGO) to deliver a VCT program to injection drug users (IDUs) in a southern Chinese city. The process data indicated the program successfully recruited and served 226 male and female IDUs in 4 months. The HIV prevalence rate of the study population was 57.5% by rapid HIV testing with a secondary rapid test to confirm. Quantitative and qualitative evaluations indicated that the VCT program was implemented appropriately and participants' HIV knowledge and safe drug and sex practices were significantly improved after participation in the VCT program. This study demonstrates the feasibility of a Chinese NGO to provide VCT for IDUs and documents the processes and outcomes of the program. There remains a great need to find additional sources to provide VCT and other HIV prevention services to IDUs and other high-risk populations in China. Chinese NGOs have the potential to fill this need.

Profile of female sex workers in a Chinese county: does it differ by where they came from and where they work?

Since the 1980s, informal or clandestine sex work in the service or entertainment industry has spread from municipalities to small towns in most areas of China. Despite recognition of the important role of female sex workers in HIV and STD epidemics in China, limited data are available regarding their individual characteristics and the social and environmental context of their work. Furthermore, most existing studies on commercial sex in China have been conducted in large cities or tourist attractions. Using data from 454 female sex workers in a rural Chinese county, the current study was designed to explore the individual profiles of commercial sex workers and to examine whether the profile and sexual risk behaviour differ by where the female sex workers came from and where they work. The sample in the current study was different from previous studies in a number of key individual characteristics. However, similarly to previous studies, the subjects in the current study were driven into commercial sex by poverty or limited employment opportunities, lived a stressful life, were subject to sexual harassment and related violence, and engaged in a number of health-compromising behaviours including behaviours that put them at risk of HIV/STD infection and depression. The findings of the current study underscore the urgent need for effective HIV/STD prevention, intervention and mental health promotion programs among female sex workers in China. The data in the current study suggest a strong association of individual profile with the economic conditions of work sites and residence status (in-province residency vs. out-of-province residency), which suggests that such efforts must take the social and cultural contextual factors of working environment (and sexual risks) into consideration.

Short-term effect of a cultural adaptation of voluntary counseling and testing among female sex workers in China: a quasi-experimental trial.

This study evaluates the efficacy of cultural adaptation of a voluntary counseling and testing (VCT) intervention, in increasing condom use and decreasing rates of sexually transmitted diseases (STDs) among a group of female sex workers (FSWs) in Guangxi, China. This intervention is modeled after the "state-of-the-science" VCT program that was developed and evaluated by the Center for Disease Control and Prevention's Project RESPECT. Four hundred FSWs were assigned to either an intervention group receiving the VCT intervention or a control group receiving standard of care STD testing and treatment. Data were collected at baseline and 6 months postintervention. Outcome measures included HIV/STD related knowledge and perceptions, condom use, and history of STDs. Five common STDs were screened and tested through clinical examination and laboratory testing to serve as biomarkers. After controlling for potential confounders and baseline differences, the VCT intervention group was significantly higher than the control group in HIV/STD related knowledge (p < .0001) and consistent condom use with clients (odds ration [OR] = 2.23; 95% confidence interval [CI] = 1.26-3.96) at 6 months follow-up. In addition, the intervention group had a significantly lower infection rate of STDs than the control group at follow-up (OR = 0.44; 95% CI = 0.24-0.80). This quasi-experimental trial provides evidence that the brief VCT intervention, through appropriate cultural adaptation, can be efficacious in increasing condom use and reducing STD infection rate among FSWs in China.

Vaginal douching, condom use, and sexually transmitted infections among Chinese female sex workers.

BACKGROUND AND OBJECTIVE: Vaginal douching has been hypothesized to increase a woman's risk for human immunodeficiency virus (HIV) infection. However, data on the prevalence of this practice and its association with condom use and sexually transmitted infections (STIs) are limited. STUDY: A cross-sectional survey among 454 female sex workers (FSWs) in a Chinese county. RESULTS: Vaginal douching was reported by 64.7% of the women. The prevalence of self-reported history of STI and that of current STI was 19.4% and 41.5%, respectively. Fifteen percent of the women reported consistent use of condoms with their clients and 8.4% with their regular partners. Vaginal douching was significantly associated with decreased use of condoms (with clients: OR = 0.31; with regular partner(s): OR = 0.22) and increased rate of self-reported STI history (OR = 1.95). However, there was no direct relation between douching and current STI. Over one third of the women believed that douching can prevent STI/HIV. CONCLUSION: Vaginal douching exposes FSWs to a high risk of STI/HIV. Medical professional and public health workers should correct women's misconception about the effectiveness of douching and discourage women from douching through educational activities.

Condom use among female sex workers in China: role of gatekeepers.

OBJECTIVE: The objective of this study was to assess the potential role of gatekeepers of establishments in promoting condom use among female sex workers (FSWs) in China. GOALS: The goals of this study were to explore FSWs' perceptions of gatekeeper attitudes and support for condom use, and to assess their association with FSWs' practice, communication, intention, proper use, knowledge of correct use, and perceptions related to condom use. STUDY: The authors conducted a cross-sectional study among 454 establishment-based FSWs in one Chinese county. RESULTS: Perceived gatekeeper support for condom use was low among FSWs. Perceived support was positively associated with condom use communication with sexual partners, condom use frequency and intention, but not associated with proper condom use among FSWs. Perceived support was significantly associated with most condom use-related perceptions (e.g., self-efficacy of condom use, barriers to condom use, and perceived peer condom use) among FSWs. CONCLUSIONS: Healthcare professionals should work with gatekeepers to create a supportive local environment for condom use in sex work establishments. Gatekeepers need to clearly articulate their support for condom use to the FSWs. Training and skill acquisition regarding correct use of condoms among FSWs will be necessary.

[Qualitative study of drug-using and sexual behaviors of drug users in Guangxi].

OBJECTIVE: To understand where and how drug-using and sexual behaviors occurred among drug users. METHODS: Twenty-five drug users were recruited from detoxification centers and communities. In-depth interview was used to collect information about drug-using and sexual behaviors. Each subject was interviewed separately and privately for about 2 - 3 hours. RESULTS: Most drug users shifted from oral taking drugs to injecting drugs in order to reduce economic burden and look for "high feeling". Reasons for not injecting among few drug users included 'perceiving information on harm of injection', 'over-dose death' or 'infection with HIV'. Most drug users knew that HIV transmit through sharing needles or having sexual intercourse without using a condom. However, needles were shared at night when drug or needles were scarce. Promiscuous sexual relationship was common among drug users. Most female drug users had engaged in prostitution but few used condoms. CONCLUSION: High-risk drug injecting behaviors and high-risk sexual behaviors were prevalent among drug users despite knowledge on HIV transmission and prevention. Thus, education alone would not work unless specific intervention programs are taken.
